To use the new 24-bit REX2 files of DOD Vol. 2 and later volumes (as opposed to the 16-bit REX2 files of Vol. 1), you need to download the latest "Rex Shared Library" extension from Propellerheads. This is true for all programs (Cubase, DP, etc.), not just those from Propellerheads. Before installing the new Rex Shared Library, you must remove ALL older versions of the Rex Shared Library from your computer. For some software applications there are multiple copies in various places on your computer. So in addition to doing a search on the hard drive, you should look through the main application folder as well. If you don't remove ALL older versions before installing the latest Rex Shared Library, then the update won't take effect and the files won't play.
